Trust-based QoS Routing Algorithm for Wireless Sensor Networks
With the rapid development of Wireless Sensor Networks(WSNs),besides the energy efficient,Quality of Service(QoS)supported and the validity of packet transmission should be considered under some circumstances.In this paper,according to summing up LEACH protocols advantages and defects,combining with trust evaluation mechanism,energy and QoS control,a trust-based QoS routing algorithm is put forward.Firstly,energy control and coverage scale are adopted to keep load balance in the phase of cluster head selection.Secondly,trust evaluation mechanism is designed to increase the credibility of the network in the stage of node clusting.Finally,in the period of information transmission,verification and ACK mechanism also put to guarantee validity of data transmission.In this paper,it proposes the improved protocol.The improved protocol can not only prolong nodes life expectancy,but also increase the credibility of information transmission and reduce the packet loss.Compared to typical routing algorithms in sensor networks,this new algorithm has better performance.
